Cause of Heavy D’s Death Revealed

Heavy D reportedly died from a pulmonary embolism – blockage in one or more arteries in the lungs – caused by deep leg vein thrombosis.

The rapper’s condition may have been escalated by a flight back to Los Angeles from the Michael Jackson tribute concert in Wales, according to TMZ.

The Los Angeles coroner’s office classified the death as “natural.”

Deep leg thrombosis is often associated with long plane flights, during which clots can form because of prolonged immobility. The clot, which forms in the leg, can move to other parts of the body.

The 44-year-old performer died Nov. 9.
